Simply price tag has made this no 1 selling device in the market but to be honest after using this device for five months I would like to suggest you guys that please dont step for xiamoi. First of all its service centre experince are rather worst than micromax. The attendant are illmannered. Phone outside design and built quality are impressive but it punctures itslef in terms of performance. Phone has a heating issue while playing games. Since its configuration lures a user to play games but it fails to keepa the promise.no fast charging available since it has a massive battery it takes ab ample of time to take full charge. Its mat black colour attract fingure print impression very badly and always give it a mess in terms of looks. Phone hangs often while playing games. So I suggest personally after my peraonal experinece to avoid buying this product.
